IMPROVEMENT IN THE MANUFACTURE 0F TRUNKS FQR RENDERING-THEM WATER-PROOF.

Specification forming part of Letters Patent No. l ,849, dated November 7, 1840.

Be it known that I, PETER GETZ, of the city of Lancaster, in the county of Lancaster and State of Pennsylvania, have invented a new and useful vImprovement on the Traveling- Trunk called the' Screw-Lid Vater-Proof Trunk, and I do hereby declare that the t'ollowingis a full and exact description.

For a useful traveling-trunk I make of tinned sheet-coppera box Aof about twentyfour inches in length, fourteen in width, and about nine in depth. On the top ot this box is fastened a board of about halt an inch thick, extending even with the side and ends of the box and covered with leather B. In the center of this top a circular hole C iscut, ofabout the diameter of ten or twelve inches, in which a brass ring D is fitted ot'about one fourth of an inch in thickness and of about tix-'e-eighths of an inch in depth. Anothery so that when this copper lid is screwed into its place the joint is completely water-tight. This box is then placed in a wooden trunk covered with leather or in a hard leather trunk I. In either case I use a raised lid, the inside of which is formed into an air-vessel K, made of tin, similar to that of the box. The key-hole L of the lock of the trunk is also secured by a small screw made in the manner above mentioned.

The advantages of this trunk are that it may remain any length of time under water without admitting any water into it, and by the air inclosed in it and that of the air-vessol in the lid gives it buoyancy sufficiently to assist a person in floating so long as he or they can bear theimmersion in Water.

The box and air-vessel can also bemade of1 PETER GETZ.
